汶川地震和芦山地震都发生在龙门山断裂带，且只相隔5年。本文利用距平方法研究发现两次强震前卫星热红外均存在升温异常，为了找出两次地震前异常的异同及强震前的热红外异常规律，本文对两次地震前的热红外异常现象进行了比较。结果表明：两次地震前都存在中、长期异常，芦山地震前存在短期异常，而汶川地震前短期异常不突出，甚至震前半年很平静；震前异常升温面积都很大，达到几十万 km2；异常优势分布区域并不在震中区域或发震断裂。

The 2008 M8 . 0 Wenchuan and the 2013 M7 . 0 Lushan earthquakes occurred on the Longmenshan fault respectively within 5 years interval. In this paper we use the departure method to analyze the observation data. We found that anomalies in the observation data of satellite thermal infrared appeared before these two earthquakes. In order to find out the similarities and differences between anomalies before two earthquakes,we compare two group data and find that the medium- and long-term anomalies appeared before two earthquakes. There are short-term anomalies before the Lushan earthquake,but there were not clearly short-term anomalies before the 2008 M8. 0 Wenchuan Earthquake. Even though a half year before the 2008 M8. 0 Wenchuan Earthquake occurred,there were not any anomalies. The total area of the abnormal warming region is up to hundreds of thousands of square kilome-ters. The main anomalies did not distribute around the epicenter areas or the seismogenic faults of these two earth-quakes.
